Office offset printer adjustable for e.g. paper thickness - has control linkage coupled to paper feeder and for adjusting cylinder spacing

摘要

Offset printing machine for office use is readily adjustable to different types and thicknesses of paper. A manually adjustable lever with click-stop positioning is connected to the paper feeder by a spring and is also connected by a linkage with the stop which regulates the spacing between the blanket cylinder and the back pressure roller. The linkage comprises a rod connected between the adjustable lever and the one arm of a swivable toothed segment whose other arm engages with a pinion on the shaft which carries the stop.
